Installing the Chassis Rails
You will need to remove the top cover and the feet to add rack rails to the chassis.
First, remove the top and right covers (top and left covers when standing as a tower
chassis) by fi rst removing the screws that secure them to the chassis. Depress
the button on the top (side if tower) of the chassis to release the cover and then
pull the cover off. Then unscrew the four feet and remove them from the chassis
(see Figure 2-2).
You can now attach rack rails to the top and bottom (now the sides) of the chassis.
First add the rack handles. Then position the inner chassis rail sections you just
removed along the side of the chassis making sure the screw holes line up. Note
that these two rails are left/right specifi c. Screw the rail securely to the side of the
chassis (see Figure 2-3). Repeat this procedure for the other rail on the other side
of the chassis. You will also need to attach the rail brackets when installing into a
telco rack.
Locking Tabs: As mentioned, the chassis rails have a locking tab, which serves
two functions. The fi rst is to lock the system into place when installed and pushed
fully into the rack, which is its normal position. Secondly, these tabs also lock the
system in place when fully extended from the rack. This prevents the system from
coming completely out of the rack when you pull it out for servicing.
